EDURE OF ROLLING Satra Strand, Sweden Application December 2, 1949, Serial N 0. 130,634 In Sweden January 11, 1946 4 Claims.

The present invention relates to the art of metal rolling and more particularly relates to a rolling mill guide.

In the art of metal rolling for instance the production of round iron, the work-piece is to be directed into the round groove by means of guides. When the work-piece is inserted between the guides, the latter must be spaced sufliciently to allow for easy insertion of the work-piece between them. The guides must also be able to clamp the work-piece at the same instant as it is caught by the rolls and to guide the work-piece while it glides between them during the rolling. Normally this guiding is effected in such a manner that one guide is mounted in a guide box and the other guide is moved towards or away from the fixed guide by means of a screw or a wedge. Fine ad ustment of the position of the Work-piece in the axial direction of the rollers is then effected by the adjustment of screws upon which the fixed guide rests, or otherwise by means of plate spacers. For every work-piece that is rolled, the guides are worn and it therefore follows that subsequent work-pieces are moved more and more in the direction of the fixed guide, that is, the workpieces are moved successively towards one side of the round groove as the rolling proceeds, whereby the rolled bar is not truly round. Coarse adjustment of the guides in the axial direction of the rollers is normally effected by displacement of the guide box proper. guides at the beginning of the rolling as well as adjustment of the same during the rolling is both time wasting and diflicult.

The present invention therefore has for an object to provide a rolling mill guide particularly rating in a guide box a laterally adjustable slide upon which is mounted a fixed guide and a movable guide.

It is a specific object of the invention to provide adjusting means for the guides, including a screw and means connecting the screw to the slide and and means are provided coupling the sleeve to the slide so that rotation of the sleeve moves the slide and thereby the fixed guide in a direction oppositeto the movement of the screw, 7

It is a still more specific object to provide in Thus, adjustment of the ,the two guides adjustment thereof is necessitated by the wearent from the following description taken in connection with the accompanying drawings, in which:

Fig. 1 shows a front view of a work-pieces, partly in section.

Fig. 2 is a side view of the same guide box.

Fig. 3 is a front view, partly in section, of a modified guide box; and

Fig. 4 is a side view of the guide box shown in Fig. 3.

In the drawings, the guide box includes a frame I screwed on to a bar in the stand. In the guide box is a slideway in which is mounted a guided slide 2, in which uide box for slidably guided in the guide nut 6 is fixed by the washer 1 that is screwed to the end plate 8 bushing 5 constitutes a, part of the second slide and in engagement with an internally threaded hole in the slide 2. grooves are respectively provided in the interior of socket II and exterior surface of the screw 9, grooves are placed two wedges 12 which are held in their position by a washer and the coil spring I3. The pitch of the threads of the screw 9 and the socket H is the same. A 9 will cause this to bear upon the support member I!) to exert force upon the loose guide 2b and to move them laterally. The socket H is turned simultaneously, and hereby the slide 2 and the fixed guide 2a are moved the same distance in the opposite direction. Since move towards each other, no

they are suffering during the rolling. The wear of the guides is compensated for by an increased tightening of the screw 9. Every lateral adjustment of the guides at the beginning of the rolling is effected solely by turning the nut 6, the slide 2, in which both guides are inserted, being moved in one direction or the other. A possible adjustment at exchange of guides of different thicknesses is efiected by removing the wedges l2 and turning the screw 9. The guide box has been tested for rolling of a plurality of profiles. An

easy and quick adjustment as well as a more exact rolling have been observed in all cases. In certain cases the use of this box construction has made it possible to substitute expensive profile rollers for rolling profiles of similar shape but difierent width by one single profile groove for all dimension.

The constructions of the guide box according to Figs. 3 and 4 show a somewhat simplified embodiment of the guide box according to Figs. 1 and 2.

The guide box I is screwed to a bar in the stand. In the guide box is a guided slide 2, in which the guides 2a, 2b are mounted. One guide 2a is adjustably fastened to the slide 2 by means of the screw 3 and the other guide 21) is loosely mounted in the slide 2. In the guide box is also mounted a second slide member 4 guided for adjusting movement in a direction laterally of the axis of the guides upon turning of the screws it which respectively bear against opposite faces of the second slide member. In this form of the invention the screw 9 is screwed into the internally threaded aperture in the outer member of the two part slide member 4, said screw actuating the support member H), which is guided in the slide 2. The screw 9 extends through the socket H, which is turnable in but axially fixed relative to the slide member 4. The other end of the socket has an external thread which engages the internal threads in an aperture in the end wall of the slide 2. In the socket II and the screw 9 are respective key grooves, in which two wedges l2 are inserted. The pitch of the threads of the screw 9 and the socket H is the same, thus when the screw 9 is rotated it bears upon the support member Hi to exert force upon the loose guide 2b and move both support and loose guide in the lateral direction. The socket H is turned simultaneously, so that the slide 2 and the fixed guide 2a are moved the same distance in the opposite direction.

A lateral adjustment of the guides is eiiected by means of the adjusting screws M. The movement of the second slide member 4 moving the slide 2, in which both guides are inserted, in one direction or the other depending on which adjusting screw is actuated.

It is therefore clear that the present invention provides a rolling mill guide in which the box structure I is provided with upper and lower parallel surfaces constituting respective slideways the axes of which extend transversely with respect to the direction of movement of the stock to be rolled. In both forms of the invention a slide member 2 including upper and lower parallel legs and a vertical connecting leg is displaceable along the slideway. A fixed guide member 2a is secured to the slide by a screw 3 extending outwardly of the box I through a slot in the upper leg thereof, and movably carried by the slide 2 is another guide member 21). Between the movable guide member and the end connecting leg of the slide is a support member 10 with respect to which the screw 9 cooperates to move the movable guide relative to the slide. In each arrangement illustrated an additional slide member is provided. This additional slide member is apertured and is composed of two elements. In Fig. l the slide 4 is cooperatively associated with the threaded bushing 5 to constitute a bearing for the socket or sleeve H and also to prevent axial movement of the socket when the screw 9 is rotated. In Fig. 1 this supplementary or additional slide member is confined between the upper and lower slideways of the box. In Fig. 3 the slide member projects through a slot in the top wall of the box and is acted upon by the screws M for adjusting movement of the main slide, the sleeve, and the guides carried by the main slide which move as a unit in either direction responsive to turning screws 14.

In the arrangement of Fig. I the bushing 5 is internally and externally threaded and the internally threaded nut B is mounted on the end plate of the guide box in such a manner that it cannot move axially relative to the end plate due to the positioning of the element 1 cooperating with the flange on the nut 5. It therefore follows that rotation of the nut 6 axially moves the bushing 5, the sleeve H and thereby the slide 2 carrying both the guide members.

It is therefore clear that the present invention provides an arrangement in which for wear takeup purposes a single adjustment comprising the rotation of the screw 9 in either arrangement provides simultaneous movements in opposite directions of the two guide members and for position adjustment prior to rolling rotation of the nut S in Fig. 1 displaces the unit comprising the slide and the two guide members, while in Fig. 3 this position adjustment is effected by the cooperation of the respective screws I l with the supplementary slide 4.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:
